Method for shaping shoe spikes

ABSTRACT

A method for shaping shoe spikes is disclosed herein, wherein the distribution of the spikes is divided into five areas, including an inside stepping out area, a thumb ball stepping area, a base area, a feedback area and an outside landing area. The spike of the outside landing area has a height less than that of a spike of the base area so that the stress resulted from foot running can be guided to the thumb ball stepping area from the outside landing area. Furthermore, the spikes of the thumb ball stepping area are shaped to be on the same tread surface and contacted with the ground at the same time so that the stress while foot running can be undertaken by the thumb ball stepping area to guide the sufficient explosive force to the inside stepping out area and further output from the inside stepping out area.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method for shaping shoe spikes to fully comply with the implementation of the foot running dynamics.

2. Description of Related Art

Spiked shoes have been widely used in the sports arena. A variety of spiked shoes having different purposes enable the athletes wearing the spiked shoes to run in the soft ground with an improving speed. However, due to the Asian climate, the sports venues in Asia are generally hard. When stepping on the hard grounds (hard grounds described herein are not cement floors) by the spiked shoes, the athletes may hurt their ankles in a lateral movement of defense, a brake or a running process due to the counterforce caused by the spikes touching the ground. Usually, there are two essential conditions of shoes to make the foot run smoothly: the thumb ball position must be slightly lower than the horizontal position; and the inside of the shoes should meet the stress guided path of the length difference between the external side and the inner side of shoes guided from the rear side to the forward side.

Unlike the sports shoes having flat soles that can bear the plantar pressures by adding a thick insole to solve problem of sagging amount, the spiked shoes having diverse length of spikes, such as soccer shoes, football shoes and the like, cannot bear plantar pressures merely by adding thick insoles. Usually, spike shoes have the same length of spikes arranged in the inner and external sides, and have a row of spikes arranged in the middle shorter than those of the inner and external sides. The spikes can step into the soil to a depth of 2-3 mm. In a process of a lateral movement and a dash, the spikes arranged in the middle have a distance from the ground and do not share the plantar pressures. Thus, counterforce caused by the spikes touching the ground may concentrate on two or three spikes of the inside thumb ball position in a lateral movement, and the stress of foot running dynamics conducts discontinuously. In such a case, the stress cannot be guided to and output from the inside thumb ball position to while foot running Moreover, the stress guided path cannot meet the status that the tread surface of the inside stepping area are slightly lower than a horizontal plane. If the spikes do not bite into the ground, a giant counteraction and resistance may be generated, resulting in negative consequences to the athletes, e.g. a slow start, a requirement of a great effort for lateral support, a delay in changing direction, and a rapid loss of muscle endurance.

SUMMARY OF THE INVENTION

In view of the above-mentioned problems, the object of the present invention is to provide a method for shaping shoe spikes. It modifies and rearranges the spikes in length to prevent hindrance to convey the stress resulted from foot running and prevent affection of the foot landing angle in a running process. Accordingly, the spikes can meet the curvature of the foot landing to be contacted with the ground in sequence and comply with the foot running process to achieve the effect of implementing the foot dynamic process semi-compulsorily. Furthermore, the spikes that do not contact with the ground originally are shaped to be on the same tread surface to share the stress uniformly, so as to achieve efficacy of effort-saving, smooth, and pressure dispersing.

Disclosed herein is a method for shaping shoe spikes distributed on an inside stepping out area corresponding to a foot thumb, a thumb ball stepping area corresponding to a thumb ball, a base area, a feedback area, and an outside landing area. The spike of the outside landing area is shaped to have a height less than that of the spike of the base area in accordance with a stress guided path while foot running so that the stress of foot running can be guided to the thumb ball stepping area from the outside landing area. Furthermore, the spikes of the thumb ball stepping area are shaped to be on the same tread surface and contacted with the ground at the same time so that the stress while foot running can be undertaken by the thumb ball stepping area to guide sufficient explosive force to the inside stepping out area and further output from the inside stepping out area.

According to an embodiment of the present invention, an inclination angle ranging from 3 to 5 degrees relative to a horizontal line is formed between the spike of the feedback area and the spike of the thumb ball stepping area after the spike of the thumb ball stepping area are shaped to be on the same tread surface.

According to an embodiment of the present invention, the height of the spike of the outside landing area in step (b) ranges from 2 mm to 3 mm in case of two spikes located on outside landing area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As showed in FIGS. 1-3, a schematic diagram, a bottom plan view and a lateral view of the first embodiment showing shoe spikes according to the present invention are disclosed. The distribution of the spikes is divided into five areas, including an inside stepping out area (1) corresponding to a foot thumb, a thumb ball stepping area (2) corresponding to a thumb ball, a base area (3), a feedback area (4) and an outside landing area (5). A method for shaping shoe spikes is disclosed herein, comprises the steps of:

(a) reserving a height of the spike of the base area (3) and taking the same as a basis reference;

(b) shaping the spike of the outside landing area (5) to have a height less than that of the spike of the base area (3) in accordance with a stress guided path while foot running;

(c) shaping the spike of the thumb ball stepping area (2) to be on a same tread surface and contacted with the ground at the same time according to the stress guided path from the base area (3) to the thumb ball stepping area (2); and

(d) forming an inclination angle X between the spike of the feedback area (4) and the spike of the thumb ball stepping area (2) as the feedback area (4) is subject to the stress guided path, so as to allow the stress guided path to be guided from the feedback area (4) to the thumb ball stepping area (2) and output from the thumb ball stepping area (2) to the inside stepping out area (1).

Preferably, the height of the spike of the outside landing area (5) in step (b) ranges from 2 mm to 3 mm in case of two spikes located on the outside landing area (5); and the inclination angle X in step (d) ranges from 3 to 5 degrees relative to a horizontal line.

Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, a foot applies a force outward obliquely while running and thus the way forward is inward obliquely. The other foot would land by the outside landing area generally to offset an oblique force and the vertical gravity. Finally, the stress is guided out from the inside stepping out area, so as to maintain a running action. Therefore, the first area of spike shoes contacting the ground is the outside landing area (5).

As shown in FIG. 2, a bottom plan view of a first embodiment showing shoe spikes according to the present invention is disclosed. The shoe spikes includes a spike A of the base area (3); a spike B and a spike C of the outside landing area (5); a spike D, a spike E, a spike F and a spike G of the thumb ball stepping area (2); a spike H and a spike J of the feedback area (4); and a spike I of the inside stepping out area (1). Usually, the traditional spike shoes have the same length of spikes arranged in the inner and external sides, and have a row of spikes arranged in the middle shorter than those of the inner and external sides. In the present invention, such spikes arrangement of the traditional spike shoes are shaped to meet foot running dynamics.

The method for shaping shoe spikes comprises the steps of: (a) reserving a height of the spike A of the base area (3) and taking the same as a basis reference; (b) shaping the spike B and the spike C of the outside landing area (5) to have a height less than that of the spike A of the base area (3) in accordance with a stress guided path while foot running; (c) shaping the spike D, the spike E, the spike F and the spike G of the thumb ball stepping area (2) to be on a same tread surface and contacted with the ground at the same time according to the stress guided path from the base area (3) to the thumb ball stepping area (2); and (d) forming an inclination angle X between the spike H of the feedback area (4) and the spike G and the spike E of the thumb ball stepping area (2) as the feedback area (4) is subject to the stress guided path, so as to allow the stress guided path to be guided from the feedback area (4) to the thumb ball stepping area (2) and output from the thumb ball stepping area (2) to the inside stepping out area (1).

Accordingly, the reservation of a height of the spike A of the base area (3) can prevent a stress from transferring to inside of the foot while the foot is stepping in front of the body which may cause plantar fasciitis due to a great pressure on the foot arch, and can enhance athlete's endurance in the sports arena. Moreover, the spike A of the base area (3) generates resistance while contacting the ground to control foot landing angle so that the inside of the foot elevate slightly and make the outside of the foot landing easily (by the spike C).

In the abovementioned step (b), the spike C can be shaped to have a height less than that of the B ranging from 2 mm to 3 mm preferably. Accordingly, the spike B and the spike C are on a same tread surface while foot landing. If the spike C contacts the ground first, counterforce generate by the spikes touching the ground may concentrate on the middle of the foot, which may reduce fluency of foot landing, produce excess resistance, increase wear and tear in the process of power transfer, and increase deviation from the direction of power flow.

In the abovementioned step (c), the spike D, the spike E, the spike F and the spike G of the thumb ball stepping area (2) are shaped to be on a same tread surface so that the four spikes of the thumb ball stepping area (2) can share stress and save power before kick-out or in a lateral movement. Because the spikes located in the middle of the shoes, such as the spike D and the spike E, are also involved in sharing stress, counterforce may not concentrate merely on the spike D and the spike E.

In the abovementioned step (d), the inclination angle preferably ranges from 3 to 5 degrees relative to a horizontal line, so as to allow the stress guided to the inside stepping area and meet the foot dynamic while stress transferred from the outside stepping area to the inside stepping area. Accordingly, the frequency of the foot fits for the frequency of the spike shoes so that the stress can be transferred to the inside stepping area simultaneously. The stress transfer rate of the spike shoes is nearly identical to the stress transfer rate of the outside of the foot while the heel elevated and the foot not contact with the ground.

If the inclination angle is less than 3 to 5 degrees, the effect of stress guide may not obvious. In contrast, if the inclination angle is much than 3 to 5 degrees, foot will flip to the inside while the outside stepping area of shoes in contact with the ground, resulting in a stress concentrating on the thumb ball area early. In such a case, the foot is still stepping in front of the body instead of stepping behind the body which is the position most suitable for kick-out by the thumb ball stepping area. Therefore, the foot arch will bear a lot of stress and disperse energy that originally provide the thumb ball stepping area for kick-out, resulting in a slow start.

Furthermore, in case of two spikes (the spike B and the spike C) located on the outside landing area, the spike B and the spike C are shaped to have a height less than that of the spike A of the base area (3). Specifically, the spike A and the spike B are shaped to have a height much than that of the spike C, and the spike D, E, I are shaped to have a height less than that of the B, H, J to form a well stress guided environment toward the inside of the shoes.

Referring to FIG. 4, a bottom plan view of a second embodiment showing shoe spikes according to the present invention is revealed. There are two spikes disposed on the outside landing area (5) and three spikes disposed on the thumb ball stepping area (2).

Referring to FIG. 5, a third embodiment showing shoe spikes according to the present invention is revealed. One spikes is disposed on the outside landing area (5) and two spikes are disposed on the thumb ball stepping area (2). Regardless of the form of setting combination of the spikes distribution, the shoe spikes must be distributed on the inside stepping out area (1) corresponding to a foot thumb, a thumb ball stepping area (2) corresponding to a thumb ball, a base area (3), a feedback area (4), and an outside landing area (5). Accordingly, the spikes can meet the curvature of the foot landing to be contacted with the ground in sequence and comply with the foot running process to achieve the effect of implementing the foot dynamic process semi-compulsorily.

Hereinafter, tens volunteer players playing soccer, frisbee, football and the like on the hard ground are recruited and recorded by the following test items:

1. time spent of the same distance (whether the time spent is shortened with the shaped spikes).

2. running distance at the same time (whether the running distance is increased with the shaped spikes).

3. time spent of changing direction five times in the same distance (whether the time spent is shortened with the shaped spikes).

The feeling of the volunteer players experiencing the shaped spikes on the test as the following:

1. It is comfortable to step on the hard ground.

2. The feeling of foot fatigue is reduced.

3. It is the best to step on an arena with moderate hardness.

4. It almost has no burden compared with the traditional spike shoes.

5. It does not need to retract force while shuttle running

6. The fatigue value is greatly reduced.

7. The shaped spikes has an improve performance.
